Gretchen is a 24-year-old-hairstylist with secrets: She likes to chase squirrels and howl at the moon. She's also not really 24.

When one of her coworkers turns up dead in the salon, she suspects that the murderer isn't entirely human. When another stylist is murdered, and then another, she goes on the prowl. A circus with a secret side show catches her attention, as does her former pack, and a group of visiting vampires.

Her only outlet is her music, but that will only keep her wolf on a leash for so long with a killer on the loose.
